application November as, isn. serial No. stesso This invention relates to refrigerators and more Particularly to an improved construction of doors for refrigerator cabinets and the like. One of the important objects of this invention 5 is to provide a refrigerator cabinet door so constructed that it may be quickly and economically manufactured and assembled.. l w 'l'he several objects. advantages, and novel details of construction of thisv invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing, wherein.

` Figure 1 is a perspective view of a refrigerator cabinet having a door constructed in accordance Figure 2 isnan enlarged transverse sectional view through the door; and- Figure 3 is an enlarged vertical sectional'vievvr throughsthedoor.'

' Referring now more particularly to the drawwherein like reference characters indicate like parts,- it will be noted that the door com-- prises metal panels 'lli and II', here shown as the 'outer and inner metal 'panels respectively of thel The outer panel has 'a pair of it'sfopposed edge shere shown as the vertical edges, formed with channels by shaping the edges of the panel I0 with open returned bent portions. W AThe reference character' I3 indicates'la 'pair of post `members or strips, preferably of wood. whichare associated with'the vertical edges of the panel It by engaging snugly in the channels I2 with which this panel' `Ill isprovided. As.

t shown, each post member Il is preferably formed with a`rabbet^ Ii/the reduced portions f` the Arabbet ntting-in the channel I2. 'gy means of l this construction, the edges .of the door are shaped to properly overlapthe opening as will be apparent.

40 The 'reference character Il' substantially the same thickness as the door, so

indicates a panel s .of/insulating material which isadapted to Aex` manner illustrated herein, or in any other suitable way.

From the foregiing it willibe apparent that the door may be readily assembled lbecause the post niembers or strips I3 are first assembled with the outer panel 1I0 by being snugly engaged in the channels I2 thereof, and these post members then provide means for subsequently attaching insulating p anel 'I5 and lthe inner panel ii. N o

framing is'required as the insulating material I5 10 extends -to the extreme^ top andbottom edges of. thedoor. Obvious modications may suggest themseives to those skilled in this art and to this end reservation' is made to make such changesr as may 15 come within the.purvlew of the accompanying claims. u l i v What I claimas my invention is;

i. A refrigerator door comprising inner and outer spaced metal panels, a one piece insulating 20 'slab extending the -full width and depth of the door and having vertical recessed portions along. opposite vertical edges thereoff'a pair of pillars housed in said recessed yportions and having angularly related inner faces thereof overlapped by g5 said slab, and means'v ncealed by 'said panelszfor fastening together y vslab and pillars to form a self-sustaining wall structure' between said panels for supporting the same. j'

2. A refrigerator-doorl comprising inner and 30 outer spaced metal panels, a one piece insulating slab extending the full width and depth of the door 'and having vertical recessed portions along opposite vertical edges thereof. a pair ofpillars housed in said recessed portions and having an- 35 gularly related inner; faces thereof overlapped by s'aid slab, and means concealed by said panels for fastening together said slab and pillars toform a self-sustaining wall structure between said panels for supporting the same, one' of said pan- 4o els'being fastened directly to said pillars at the jamb faces of the door.

3.' A' refrigerator` door 'comprising inner and l outer spaced 'metal panels, a one piece insulating Y slab extending the full width and depth ofthe I door and havingvertical recessed -portions along vopposite vertical edges thereof,'a pair of pillars v housed in said recessed portions and 'having an- 'gularly relatedl inner faces y'thereof overlapped by said slab, and means concealed by said panels 5o for fastening together said slab and pillarsto form 'aaai-sustaining wall structure betweenj said panels for supporting the same. one of said i l panels-being fastened directly to said'pillarsa the iamb faces ofthe door, and the other pane j vhaving return bent edge portions formlngchannels to receive projecting edgeions of the pillars at the'jamb faces of the door. i
